Core tip
During the 13th five-year period, new highways operated over a distance of 2100 km, extending to remote mountainous and ethnic areas. At the end of 2020, the sichuan highway was the country's first-largest mileage, with highways operating more than 8100 kilometres and achieving “municipality”。
During this period, my province also built a number of prestigious domestic and international super-engineering and demonstration projects, such as the yakan high-speed river crossing bridge, the chestnut tunnel and shinagawa road。
Strong science and technology support is essential to the continued spread of the internet and to the emergence of excellence。
The sichuan daily news is full of reporters
At the beginning of the new year, sichuan transport received a scientific and technical “gang kit”: the provincial science and technology department published the findings of the second sichuan provincial engineering and technology research centre in 2020, and the sichuan road design institute declared that the sichuan provincial centre for monitoring and strengthening of engineering and technology had been successfully approved as the 1st provincial engineering and technology research centre in sichuan, 2021, with the aim of opening the door to “1455”。
At the end of 2020, the sichuan highway was the country's first-largest mileage, with highways operating more than 8100 kilometres and achieving “municipality”. Over the past five years, sichuan transport science, technology and innovation platforms have grown from three to 10, and innovation has driven strong development。
Science and technology are the first productivity, ranging from “difficult” to “national first”, and what are the codes of innovation that support transport?
A new process to support the introduction of new technologies to address construction challenges
In january, the akam county, which is cold and cold, is under construction in the severe cold of less than 10 degrees celsius. This is the first freeway route from sichuan to qinghai, the first high-altitude highland highway in my province, with a total altitude of more than 3,000 metres across the line, 45 per cent of the sections above 3,500 metres above sea level, an average annual temperature of 1. 4°c along the route, and a valid construction period of only six months throughout the year。
Low oxygen, high temperatures, high altitude and short construction periods pose many challenges. In addition to increasing the input of personnel and equipment and extending the period of effective construction, the director-general of the kuma high highway corporation, ken yong, presented the introduction of new technologies and processes to address construction challenges, such as the construction of several bridges of the same type as the wenchuan bridge。
On the wenchuan-malcan highway, the first bridge in the country, the all bridge does not need a template, was built in 2019. Its plant chemical productivity reached 80 per cent, the steel structural parts were produced centrally in the plant, and the construction site, dey, was assembled and then transported to the bridge site for installation; the site workforce was reduced by 70 per cent and the duration was reduced by one quarter。
“it is the `scientific bridge' of the ministry of transport and communications and the ministry of transport and communications.” the designer of the bridge and the chief engineer of the sichuan road design institute stated that the site of the bridge was characterized by a harsh climate and a poor construction environment, in the core of the wenchuan earthquake. They built the country's first pre-resilient concrete bridge with the technical accumulation of steel concrete bridges, which have been studied and promoted by the roadhouse for more than 30 years。
From planning surveys to construction, sichuan transport systems continue to explore innovations and gain extensive experience. In view of sichuan's technical advantages in this regard, on 19 september last, china's academy of engineering, under the leadership of zhang xii gang, built the national centre for engineering research and research, and established its first sub-centre in sichuan to build an innovative platform for “product research” and conduct in-depth research on disaster prevention and mitigation packages for mountain bridges。
This sub-centre was launched on the second day of its existence as a “real battle”: a two-way disruption of highways and national roads due to the collapse of mountains near the yassi highway, which was dispatched by the provincial department of transport and communications, and a team of experts from the sub-centre went to the field to guide the rescue and the breakout. The group also built an early warning system for intelligent monitoring using the autonomously developed “engineered structural security intelligence monitoring cloud”, providing all-weather security alerts for on-site crashes and enabling emergency crews to carry out work safely, which was completed in just six days。
“technology and innovation are the strongest pillars for building roads and bridges.” according to the relevant head of the department of transport and communications. During the 13th five-year period, new highways were opened in the province at a distance of 2,100 km, with an average investment of 170 million yuan per km, twice as much as during the 12th five-year period, extending to remote mountainous and ethnic areas. A steady stream of innovation has driven the road network to build a number of well-known super-engineered and demonstration projects at home and abroad, such as the yacon high-speed river crossing bridge, the tunnel of the tunnels of the chestling hills and the shingawa nine road。
A team of scientific research platforms to gather and develop talent to apply results to building medium
What was the greatest change in sichuan's technological and technological innovation in transport over the past five years? The “standing of the platform!” came out of the mouth of the chief of the section of the department of transport and communications。
During the period of “1355”, the ministry of transport and communications of sichuan province increased the number of scientific research platforms from 3 to 10, highlighting the strengths of the same type of centres. The development of a scientific platform has provided a vehicle for applied research and conversion of results and has brought together and developed a talent pool。
Through bim (building information modelling) technology, projects such as highways can be “on-line” and can visualize construction progress and difficulties. This information technology has been used in a number of transport projects in the province, including survey design, construction and operational maintenance. Sichuan was the first country in the transport sector to initiate bim technology research and applications。
In 2015, when jo min, chief engineer, sichuan transport design institute, founded the bim centre of sichuan transport design institute, bim was still new in the field of transport. In 2017, the bim centre of the transport institute was approved as an industrial research and development centre of the ministry of transport, accelerating the full application of bim technology to priority transport projects such as the sichuan highway and the waterway, and leading three technological waves in the industry。
At the end of last year, jo ming was selected as the “15 innovatives of the 2020 platform for priority research in transport”. But his greatest achievement is that the bim center has grown from a small number of people who were formed to nearly 40 full-time r & d staff, creating a complex pool of professionals covering a wide range of areas, including roads, water transport, computers, and so forth. “we have set up a pool of talent to meet the age of the internet industry in transport construction.”。
In the middle of the winter season, the road from the kawaji temple to the kowloon trench was white, but there was no snow on the road and the car remained open. "we have introduced new technologies against ice condensing." the senior engineer of the sichuan road design institute released his doubts。
The new technology was developed by the highway complex itself. In my western province, which is high above sea level, “a mountain of four seasons and 10 days”, the winter road has been characterized by frequent and highly volatile ice and snowfall. The road yard has developed a road surface for auto-regulating the release rate of low-ice point materials in accordance with climatic conditions, allowing for the rapid release of de-icing agents during the winter, supported by the technology of loop thermal tubes, which, like the installation of electric heat blankets in the interior of the road, achieves intelligent control in conjunction with a road ice and snow disaster early warning system, which starts before ice and snow, melts the ice early and reduces car hazards。
The director-general of the sichuan road design institute, mr. Luo yu hong, made a presentation on the development of two departmental research and development platforms based on the “centre for research and development in the construction and conservation of roads, materials and equipment sectors in the transport and transport industry” “landworks and conservation engineering laboratory for road structures in sichuan province”, the establishment of a national advanced road research and development site known as the “road hospital” and the development of a team of “road doctors”, the results of which were used in the design of new road construction and maintenance and maintenance on more than 6,000 kilometres of highways throughout the province. “part of the core technical and research results are gradually being developed for engineering and industrial extension”
One direction of scientific research around critical technologies and critical issues
On the eve of the approval of the technical research centre for monitoring and reinforcement of road structures in sichuan province, the ministry of transport and communications issued a programme of action for the rehabilitation of roads and bridges at risk, which explicitly requires that four or five types of bridges on roads be “eliminated” during the “145” period, with the proportion of bridges i and ii accounting for more than 90 per cent。
Yao, minister of science and technology, sichuan road design institute, has just told journalists that sichuan highway traffic networks are the largest in the country, transiting many of the mountains or valleys, growing up bridges and high slopes, are well-structured and large-scale, and have long-term resilience to natural disasters such as earthquakes, landslides, landslides, landslides, and mudslides. “as the road network is perfected and saturated, the road infrastructure is becoming ever larger, the need for the road transport industry will have to shift gradually from `building' to `care”
As the main force in the design of surveys in the area of road infrastructure in my province, the sichuan road design institute has, over the past five years, established a number of new scientific research platforms, which have led to the establishment of three different types of scientific research platforms in the three priority areas of the national centre for engineering research, the industrial research and development centre, the post-doctoral research station, the provincial centre for engineering and technology research, the provincial engineering laboratory, and the state and ministry departments, which have established separate “centres” in such areas as concrete bridges for steel pipes, and disaster prevention and mitigation for mountain bridges, with a greater focus on key technologies and priority issues。
In 2020, our two new transport industry research and development centres focused on intelligent applications。
In may 2020, the joint operation of the sichuan iron tile group, xu jie group and qinghua university for the operation of a group of unmanned rollers was successfully tested in the high-speed and regional sections of the road, which represented a major breakthrough in the intellectualization of the sichuan infrastructure project. Sichuan tile group has also been successful in declaring a “research and development centre for automated operational technologies in transport and communications” to study the use of unmanned equipment, remote construction controls, multi-aerial autonomous operations, standardized construction of transport engineering, intensive construction and improved quality and efficiency of infrastructure development in the western region。
The centre for research and development in the satellite technology transport industry, as declared by sichuan skycorp, will use forward technologies such as satellite communications, navigation and remote sensing to enhance the safety monitoring of critical transport infrastructure, real-time monitoring of transport vehicle locations, traffic network operational status management, synchronized updating of transport data, and so forth. In other words, real-time monitoring of roads, bridges, tunnels, transport vehicles, etc., by means of satellite technology, ensures operational safety through early warning。
“in the coming years, our research will focus primarily on the special and difficult problems facing transport development in sichuan.” according to phuket, greater research on science, technology and innovation will be focused on the transport power country pilot project, disaster prevention and mitigation on the sichuan highlands road, intelligent transport, etc。
